THOMAS C. CONRAD, OF PHILADELPHIA, PENNSYLVANIA.

TOY ENGINE.

SPECIFICATION forming part of Letters Patent No. 433,275, dated July 29, 1890.

Application filed April 18, 1890 To all whom it may concern:

Be it known that I, THOMAS C. CONRAD, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and Improved Toy Engine, of which the following is a full, clear, and exact description.

The object of the invention is to providea new and improved toy engine which is simple and durable in construction and can be very cheaply manufactured.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out. in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side e evation of the improvoment. Fig. 2 is a plan view of the same. Fig. 3 is an enlarged sectional plan view of part of the improvement. Fig. 4 is an enlarged plan View of a modified form of the same. Fig. 5 is a perspective view of the eccentric strap and rod. Fig. 6 is a perspective view of the guideways. Fig. 7 is a plan view of the valvestem. Fig. 8 is a perspective view of the cross-head, and Fig. 9 is a transverse section of the improvement on the line a: a: of Fig. 1.

The improved toy engine Ais provided with a stick B of suitable length and adapted to be taken hold of at one end and supporting at its other end the engine proper. The lat ter is provided with a driving-wheel O, journaled at the lower end of the stick B and at one side thereof, either in the manner shown in Fig. 3 or as illustrated in Fig. 4.

As shown in Fig. 3, the hub D of the driving-wheel O fits into a transverse opening 13, formed in the stick B, and at the outer end of the said hub is held a washerF, over which is bent one end of a pin E, riveted to the drivewheel and passing centrally through the hub of the same.

As shown in Fig. l, the drive-wheel C is mounted to turn on a screw G, screwing transversely into the lower end of the stick B. On the front face of the drive-wheel C is pivotally connected the pitman II, pivoted on the front face of the crosshead I, provided on its Serial No. 348.475. (N0 model.)

top and bottom with a longitudinally-extending groove I, fitting onto parallel rods or guideways J, preferably formed of a single piece of wire, as is plainly illustrated in Fig. 6, the middle or bent parts J of the said rodsbeing secured to the side of the stick B by suitable staples K. (See Figs. 1 and 2.)

The outer ends of the rods J are secured to the inner end of a cylinder L, fastened by suitable means to the said stick B. From the cross-head I extends a piston-rod N, passing into the cylinder L and of sufficient length as not to disconnect from the cylinder when the cross-head I is in its outermost position.

On the rear face of the drive-wheel O is secured or formed an eccentric 0, over which passes an eccentric-strap P, formed, with the eccentric-rod P, of one piece of wire, as is plainly shown in 5. The end P of the rod P is bent inward and forms a pivot for the eccentric-rod, being connected with one end of a lever Q, fulcrumed on a pin Q, secured to the side of the stick 13. The upper end of the lever Q is pivotally connected with a valve-stem R, passing into a steam-chest S, formed on top of the cylinder L.

It is understood that a piston is not used in the cylinder L, nor a valve in the steam-chest S, as the two parts referred to would not be visible.

The device is used as follows: The operator takes hold of the upper end of the stick B and rests the periphery of the drive-wl1eel C on the ground or floor, and when the operator now moves forward and slightly presses on the stick B, so as to hold the driving-wheel C in frictional contact with the floor or ground, then the said drive-wheel turns, and by the pitman II imparts a reciprocating motion to the cross head I, moving the piston-rod N. The turning of the drive-wheel C also imparts motion to the eccentric P, which, by its rod P, imparts a swinging motion to the lever Q, thus imparting a sliding movement to the valve-stem R. It will thus be seen that the movement of the exterior parts of the steamengine can be readily seen and understood by a child using the toy in the manner specified. The driving-wheel C is preferably counterbalanced, as illustrated in Fig. 1.

Having thus fully described my invention, I

claim as new and desire to secure by Letters Patent- 1. A toy engine comprising a stick, a drive- Wheel jonrnaled at one end of the said stick,

guideways secured 011 the said stickand in which slides the said cross-head, a piston-rod held in the said cross-head, a cylinder secured to the said stick and into which passes the said piston-rod, an eccentric held on the said drive-Wheel, an eccentric strap and rod connected with the said eccentric, a lever pivoted on the said stick, a valve-stem pivotally connected with the said lever, and a steam-chest held on the said cylinder, substantially as shown and described.

THOS. C. CONRAD.
